I'm still trying to successfully make the transition to a stable, well-planted tank.
My problem is green algae, of the hard/slimy persuasion (nothing fuzzy). It covers the glass and is difficult to scrape off. It also covers the gravel, the equipment, etc. And is making headway on the some plants, as well as the wood shrimp...
I believe this problem is due to persistently high nitrates, but whatever I do, I simply CANNOT keep the nitrates under 10ppm without 30% DAILY water changes. Skipping changes for a few days results in rapid and progressive increase of nitrate levels and algae growth. Level seems to climb about 10ppm per day.
Here's all the parameters I can think to list. I'll provide any other needed info on request. Please help!
* 10 gallon glass tank
* 46w Lighting (2x 23w 5000k spiral compact fluorescents, in a standard incandescent hood, inside painted white, run 8hrs. daily)
* Heater, set to 76F
* Aquaclear 20, set to lowest flow
* Generic "Nanofilter" (made for 5g tank)
* DIY CO2 (yeast fermentation) injected into Nanofilter intake
* Plain gravel, no decorations whatsoever
* 12-15 small ghost shrimp
* 1x Wood Shrimp
* Malaysian trumpet snails (many)
* Pond snails (not so many, still more than I'd like)
* Male Betta
* 2x small Gold Barbs
* 3x small Green Corydoras Catfish
* 2x Otocinclus
* Hornwort, anachris, cabomba, bacopa, moneywort, water wisteria, banana plant, aponogetons, more. Heavily planted; plant growth is good, moderate pearling especially on faster growers
* Few drops of Ammo-Lock with every water change
* PMDD (ingredients from Greg Watson, no nitrate/phosphate added in my mix)
* I'm blessed with excellent tapwater. pH around 8.4. Tests 0 for ammonia, nitrite, nitrate, phosphate. No chlorine/chloramine detectable by taste or smell. No other flavours/odors/colors.
Current Tank Water Parameters:
* 0 ammonia
* 0 nitrite
* 20-30ppm nitrate
* 2ppm phosphate
Right now, very very minimal. I'm trying to encourage the fauna to eat the snails/algae.
Forgive the horrid photography, but it should give you some idea of the level of planting in my tank. (It's also the 1st ever posting of my tank!) I thought plants were supposed to EAT nitrate, why is my nitrate level so out of control?
Pulling his hair out along with the algae,
